Single-Sided Deafness and Cochlear Implants: Performance in a Novel Combined Speech-in-Noise and Localization Task.

ABSTRACT:

Objective

This study aims to analyze the impact of single-sided deafness (SSD) on listening behavior to evaluate sound localization ability, speech-in-noise performance, and quantifying and comparing compensatory head movements in individuals with normal hearing (NH) and SSD, with and without a cochlear implant (CI).

Study design

Nonrandomized, prospective, human-subject study.

Setting

Tertiary academic medical center.

Methods

NH, SSD, and SSD-CI subjects were presented with Harvard IEEE sentences at varying target azimuths in a darkened, semi-anechoic chamber in background noise while head position was monitored. Head movement (total absolute head displacement, onset delay, and response time), localization accuracy, and speech-in-noise performance were analyze
